摘要
推广了最小光程原理.假定如果选取全局时间对准的坐标系,即度规场满足g0i=0,则光的真实路径使坐标时差取极小值.据此重新得到光经过太阳表面的引力偏折角α=4GM/r=1.75″,与假定光沿测地线运动导出的结论相同.这实质上是在广义相对论条件下,对不存在超光速粒子的有力支持.此外,还提供了一种计算光传播路径的方法.
The minimum time principle was generalized. It is assumed that in global time zeroed (coordinate, which fits (g_(0i)=0),) the optical path makes the coordinate time interval minimum. According to this assumption, the deflection angle of light pass by the sun surface is α=4GM/r=1.75~″, which is the same as that obtained (before.) This is essentially a sustaining of the no super-light velocity principle in general relativity. The basic assumption about the optical behavior is proposed, so it is totally a new theory. A method was given in calculating the optical path, which may be helpful for studying the light transition in (cosmic.)
